MGM

MGM (Macrophytes Growth Model) is a process-based, eco-physiological model simulating the growth of submerged macrophytes under different environemntal conditions. MGM is a simplified re-implementation of Charisma 2.0 (van Nes et al. 2003) in Julia language.

For documentation, see:

docs/ODD.md "Overview, Design concepts, and Details" document describing the concept of the model including differences between MGM and Charisma 2.0.
Charisma 2.0 A comprehensive description of Charisma 2.0 including the model's manual.
USAGE.md how to set up and run simulations with MGM.

Folder structure:

data Mapped distribution of macrophyte species from Bavaria. Data source: Bayerische Landesamt für Umwelt
doc Documentation of the model.
experiment Exemplary workflow to run the model from R. Script runs all species in one lake per loop and writes output per lake.
input_examples Exemplary input files. To run the model, the folder has to be renamed in input.
model Source code files of the model.
optimizer Workflow to optimize the model by finding species specific parameter combinations.
sensitivity Workflows for local and global sensitivity analysis.

Functions Origin of functions is marked within the code.
